DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 2 for a frame structure for mounting a liquid crystal display panel in accordance with the present invention, the frame 20 is comprised of two long sides 21 and two short sides 22, and a 45-degree diagonal is formed at connecting ends 211, 221 of the long side 21 and the short side 22, and a rectangular frame is formed by connecting the two long sides 21 and two short sides 22 through the connecting ends 211, 221, and a connecting base 23 disposed separately at the four corners of the frame 20 is applied with a bonding technique to constitute the whole structure of the frame 20 as shown in FIG. 3.

The connecting base 23 has a top 231 and two adjacent longitudinal sides 232, such that after the two long sides 21 and the two short sides 22 of the frame 20 are combined to form a rectangular frame, a connecting base 23 disposed separately at four corners of the frame can be used for attaching the top 231 and the longitudinal sides 232 of the connecting base 23 to the lap joint position of the long side 21 and the short side 22 of the frame 20 by a bonding technique to form an internal angle, so that the bonded area can be larger to enhance the boding strength.

Referring to FIG. 4 for a frame structure for mounting a liquid crystal display panel in accordance with the present invention, the frame 20 is comprised of two long sides 21 and two short sides 22, and the long sides 21 and the short sides 22 form connecting ends 211, 221 to lap and connect the two long sides 21 and the two short sides 22 into a rectangular frame by using the connecting ends 211, 221, and a bonding technique is adopted at the connecting ends 211, 221 to form the whole structure of the frame 20 as shown in FIGS. 5 and 6.

The connecting end 211 disposed separately at both ends of the long side 21 is substantially in an L-shape right angle, and the connecting end 221 disposed separately at both ends of the short side 22 forms a first lap joint 222 substantially in a step-shape and disposed at the top of the short side 22, and a second lap joint 223 substantially bent in a right angle and extended from a longitudinal side proximate to the first lap joint 222. When the connecting ends 211 of the two long sides 21 are engaged with the connecting ends 221 of the short side 22, the first lap joint 222 of the short side 22 is lapped onto the bottom of the top of the connecting end 211 of the long side 21 and the second lap joint 223 of the short side 22 is lapped onto the internal side of the longitudinal side of the connecting end 211 of the long side 21. Due to the step-shape design of the first lap joint 222, its drop is precisely equal to the thickness of the top of the long side 21, the long sides 21 and the short sides 22 of the rectangular frame so formed after the lap connection by a bonding technique can be fixed by the connecting ends 211, 221 and the first lap joint 222 and the second lap joint 223 of the short side 22, so as to enhance the bonding strength and reduce the damage produced by transversal and longitudinal stresses. In the meantime, the connecting ends 211, 221 formed after lapping the long side 21 with the short side 22 are flat and smooth without causing any inference by protrusions or recessions, so as to constitute the whole structure of the frame 20 as shown in FIG. 5.

The connecting end 211 at an end of the long side 21 uses a first lap joint 222 of the connecting end 221 at an end of the short side 22 to lap with the bottom of the top of the connecting end 211 at an end of the long side 21, and the second lap joint 223 of the connecting end 221 is lapped onto the internal side of the longitudinal side of the connecting end 211 at an end of the long side 21. The connecting end 211 at another end of the long side 21 uses the first lap joint 222 of the connecting end 221 at another end of the short side 22 to lap with the bottom of the top of the connecting end 211 at another end of the long side 21, and the second lap joint 223 of the connecting end 221 is lapped onto the external side of the longitudinal side of the connecting end 211 at another end of the long side 21. In the meantime, a bonding technique is adopted, such that a diagonal of the whole structure of the frame 20 is folded, and another diagonal of the second lap joint 223 of the short side 22 is hooked at the external side of the longitudinal side of the long side 21 as shown in FIG. 6 to enhance the strength for bonding the long sides 21 and the short sides 22 of the frame 20.

Referring to FIG. 7 for a frame structure for mounting a liquid crystal display panel in accordance with the present invention, the frame 20 is comprised of two long sides 21 and two short sides 22, and the long sides 21 and the short sides 22 form connecting ends 211, 221 to lap and connect the two long sides 21 and the two short sides 22 into a rectangular frame by using the connecting ends 211, 221, and a bonding technique is adopted at the connecting ends 211, 221 to form an overall structure of the frame 20 as shown in FIG. 8.

The connecting end 211 disposed separately at both ends of the long side 21 is bent into a right angle and extended from the top of the connecting end 211 to form a lap joint 212, and the lateral side of its longitudinal side forms an interval with the lap joint 212. The step-shape first lap joint 222 is formed at the top of the connecting end 221 disposed separately at both ends of the short side 22, and the first lap joint 222 is bent into a right angle downwardly to form the second lap joint 223, and a junction 224 is bent into a right angle and extended from a longitudinal side proximate to the first lap joint 222. The first lap joint 222 and the second lap joint 223 form an interval with the longitudinal side of the short side 22, and the interval is precisely equal to the thickness of the lap joint 212 of the connecting end 211 disposed separately at both ends of the long side 21. The lateral side of the longitudinal side of the long side 21 and the lap joint 212 form an interval precisely equal to the bent and extended distance of the junction 224 of the short side 22. When the connecting ends 211 of the two long sides 21 are connected to the connecting ends 221 of the two short sides 22, the lap joint 212 of the connecting end 211 disposed separately at both ends of the long side 21 is embedded into the interval between the first lap joint 222 and the second lap joint 223 of the connecting end 221 at both ends of the short side 22 and the longitudinal side of the short side 22. In the meantime, the first lap joint 222 of the short side 22 is lapped onto the bottom of the top of the connecting end 211 of the long side 21, its second lap joint 223 is lapped onto the connecting end 211 at the internal side of the longitudinal side of the long side 21, and its junction 224 is precisely connected to the interval formed between the lateral side of the longitudinal side of the long side 21 and the lap joint 212. The drop of the step-shape design of the first lap joint 222 of the short side 22 is precisely equal to the thickness of the top of the long side 21, so as to provide a smooth and flat connection. In the meantime, a bonding technique is applied to enhance the bonding strength and reduce the damages produced by the transversal and longitudinal stresses and constitute an overall structure of the frame 20 as shown in FIG. 8.

Referring to FIG. 9 for a frame structure for mounting a liquid crystal display panel in accordance with the present invention, the frame 20 is comprised of two long sides 21 and two short sides 22, and the long sides 21 and the short sides 22 form connecting ends 211, 221 to lap and connect the two long sides 21 and the two short sides 22 into a rectangular frame by using the connecting ends 211, 221, and a bonding technique is adopted at the connecting ends 211, 221 to form the whole structure of the frame 20 as shown in FIG. 10.

The top of connecting end 211 disposed separately at both ends of the long side 21 forms a lap joint 212 in the shape of a long hole, and its longitudinal side forms a U-shape indent and shallow-trench lap joint 213 and an inwardly drawn interval formed at the outer lateral side of the lap joint 212. The top of the connecting end 221 disposed separately at both ends of the short side 22 forms a first lap joint 222, and a second lap joint 223 substantially bent into a right angle and extended from a longitudinal side proximate to the first lap joint 222. When the connecting ends 211 of the two long sides 21 are connected to the connecting ends 221 of the two short sides 22, the lap joints 212, 213 of the connecting ends 211 at both ends of the long side 21 are connected flatly with a first lap joint 222 and a second lap joint 223 of the connecting ends 221 at both ends of the short side 22, so as to achieve a smooth and flat connection without any interface of protrusions or recessions on the surface and enhance the bonding strength and reduce the damage produced by the transversal and longitudinal stresses and constitute the overall structure of the frame 20 as shown in FIG. 10. The design of this embodiment can avoid interference caused by components other than the screen or LCD panel 30.

Any one of the foregoing embodiments can be used together with an LCD panel 30 as shown in FIG. 11 and can be designed to meet the structural requirements of the frame of the LCD panel for combining, supporting, fixing and positioning the LCD panel 30. In the meantime, such arrangement also achieves the effects of high productivity, strength and utility rate and also avoids wasting raw materials and controls costs.
